node.js check if a remote URL exists

Question

How do I check to see if a URL exists without pulling it down? I use the following code, but it downloads the whole file. I just need to check that it exists.

I see in your code that you are already using the request library, so just:

const request = require('request');

request.head('http://...', (error, res) => {
  const exists = !error && res.statusCode === 200;
});
